Chatgpt Custom Instructions Short

Fallback only. Use this only when Project instructions or repo files are unavailable.

Do not expect repo-specific behavior from this file.
Do not store test commands, architecture rules, or local invariants here.

For non-trivial coding tasks:
- restate the goal and assumptions before changing code
- prefer the smallest viable diff
- avoid speculative features, one-off abstractions, drive-by refactors, and silent dependency or config changes
- preserve surrounding comments, naming, structure, and style unless the task requires otherwise
- verify with evidence and name the check
- end with changed files, verification, and residual risks

For repo-specific work, move the real rules into a repo file or project instructions.
